Question

Researchers have shown the density d(x) of the Dead Sea brine (in g/cm3) during evaporation can be estimated by the function below where x = proportion of the remaining brine, 0 ≤ x ≤ 1. (So x = .25 would mean there is 25% of the brine remaining.) (4) d(x) = 1.66 - .90x + .47x2 Find the absolute max density and the absolute min density, and give the x values at which they occur. Check all possible candidates! If there is a tie, write all answers. Use 3 decimal places. Absolute max __________ at x = _____ Absolute min __________ at x = _____
